Great info. Do you mean this one:

With ZFS on Linux (ZoL) and BTRFS in the horizon, it seemed as such a
script would be nice to separate OS from the data. With ro CF/USB with
an encrypted data volume implemented in Owl would indeed be awesome!

Thanks that you appreciate interest in new features. Have you ever
though to HAMMER filestystem from DragonflyBSD to port? I am
optimistic that Owl team could port HAMMER to Owl (as you already have
ported several of the BSD utilities).

Though HAMMER is not as feature rich as ZFS (does not have a volume
management but uses LVM), but I feel it safe to be in the BSD userland
than the rogue stuffs under Oracle. On top of that HAMMER uses much
less memory to do the same stuffs that ZFS can do. The only feature
lacking is master-master replication whereas master-slave replication
is already there.

The following could be some links:


It seems hammer2 will have some improvements over hammer1. Matt Dillon
has already released a roadmap on hammer 2 last month at

I would indeed love to see HAMMER happen in Owl to integrate
enterprise grade security with an enterprise grade storage system to a
new level! ;-)

Let us make Owl-enterprise-ready! ;-) Just my two kopeks!
